Structural biology and engineering of neuronal signalling

RESEARCH

The interests of our team lay at the interface of structural biology, protein engineering, and cellular neuroscience. We aim to understand molecular principles of neuronal signalling in health and disease, and to translate these to the cellular and organismal level.

We use mammalian protein expression, protein chemistry, biophysical methods, X-ray crystallography and cryo-electron microscopy to study the interaction determinants and structures of synaptic protein complexes involved in neurodevelopmental disorders and neuronal disease. We use combinatorial methods and protein engineering to discover novel binders and manipulate protein sequence, structure and function, both to facilitate structural studies as well as enable therapeutic targeting of these complexes.

Join us! We currently have a 3-year postdoc position available!

TEAM LEADER: Jonathan Elegheert

After studying medicine (BSc) and biochemistry (MSc), I obtained my PhD in 2012 from Ghent University (Belgium), where I studied the structural biology of Colony-Stimulating Factor 1 (CSF-1) cytokine signalling in the lab of Prof. Savvas N. Savvides as a FWO (Research Foundation - Flanders) doctoral fellow. In 2012, I joined the Division of Structural Biology (STRUBI) at the University of Oxford (United Kingdom) as an EMBO- and Marie Curie Actions-funded postdoctoral fellow. There, I transitioned into molecular neuroscience and investigated the structural biology of synaptic organizer protein complexes, in the lab of Prof. A. Radu Aricescu. In 2018, I joined the IINS as a team leader.

FUNDING

Our work is funded by an Initiative of Excellence (IdEx) Junior Chair (University of Bordeaux) and a Neurocampus starting grant (Conseil Régional de la Nouvelle Aquitaine).
